Description
Technical Field
The application belongs to the technical field of glasses cleaning liquid, and particularly relates to a glasses cleaning liquid.
Background
Spectacles are simple optical devices made for correcting eyesight or protecting eyes, and consist of lenses and a spectacle frame. The glasses for correcting the vision comprise four types of glasses for myopia, hyperopia, presbyopia and astigmatic. The glasses are not only tools for protecting eyes, but also a cosmetic ornament.
For most people, the glasses are necessities of life, the glasses are vital to the life of people, the glasses need to be cleaned and wiped after being worn for a long time, and the sight of the glasses is affected by dust and grease stuck on the glasses. People often only use the glasses cloth to wipe the glasses for convenient use, but the glasses can be scratched after a long time, and the glasses cloth cannot be wiped cleanly sometimes. There are also a lot of glasses cleaning solutions on the market, but these cleaning solutions all can only be applicable to the glasses of a material, some are only applicable to the lens of glass material, some are only applicable to the lens of resin material. Thus, special attention is required for use, and the use is inconvenient. Some cleaning solutions contain weak toxicity, are not environment-friendly enough and are unsafe to use; although the lens can be cleaned temporarily, some damage is also caused to the lens. Meanwhile, many existing glasses cleaning liquids can generate harmful substances in the preparation process, cause pollution and have great harm to human bodies.
Disclosure of Invention
In view of this, the technical problem to be solved by the present application is to provide a glasses cleaning solution, which is used to solve the problems of the previous glasses cleaning solution that the cleaning is not clean, the sterilization efficiency is low, and the contamination is strong.
In order to solve the technical problems, the invention discloses an eyeglass cleaning solution which is prepared from the following raw materials in parts by weight:
20-40 parts of glycerol, 15-25 parts of aloe extract, 13-17 parts of coconut oil derivatives, 11-18 parts of xyloside derivatives, 2-5 parts of sodium alginate, 2-6 parts of ethylene glycol monobutyl ether, 1-3 parts of fatty acid polyoxyethylene ether, 0.8-1.2 parts of lemon oil, 5-7 parts of anionic surfactant and 800-1000 parts of deionized water.
According to an embodiment of the invention, the composition is prepared from the following raw materials in parts by weight:
25-35 parts of glycerol, 16-23 parts of aloe extract, 14-16 parts of coconut oil derivatives, 13-16 parts of xyloside derivatives, 3-5 parts of sodium alginate, 3-5 parts of ethylene glycol monobutyl ether, 1.5-2.5 parts of fatty acid polyoxyethylene ether, 1-1.2 parts of lemon oil, 6-7 parts of anionic surfactant and 850-950 parts of deionized water.
According to an embodiment of the invention, the composition is prepared from the following raw materials in parts by weight:
30 parts of glycerol, 20 parts of aloe extract, 15 parts of coconut oil derivatives, 15 parts of xyloside derivatives, 3 parts of sodium alginate, 4 parts of ethylene glycol monobutyl ether, 2 parts of fatty acid polyoxyethylene ether, 1 part of lemon oil, 6 parts of anionic surfactant and 900 parts of deionized water.
According to an embodiment of the present invention, the coconut oil derivative is one or two of sodium cocoyl sulfate and cocamidomonoethanolamine.
Compared with the prior art, the application can obtain the following technical effects:
the aloe extract and the coconut oil derivative enhance the cleaning effect and remove surface grease, and the xyloside derivative effectively removes mites and bacteria, improves the sterilization efficiency and reduces pollution.
Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.
Detailed Description
The following embodiments will be described in detail with reference to the accompanying examples, so that how to implement the technical means for solving the technical problems and achieving the technical effects of the present application can be fully understood and implemented.
The invention discloses a glasses cleaning solution which is prepared from the following raw materials in parts by weight:
20-40 parts of glycerol, 15-25 parts of aloe extract, 13-17 parts of coconut oil derivatives, 11-18 parts of xyloside derivatives, 2-5 parts of sodium alginate, 2-6 parts of ethylene glycol monobutyl ether, 1-3 parts of fatty acid polyoxyethylene ether, 0.8-1.2 parts of lemon oil, 5-7 parts of anionic surfactant and 800-1000 parts of deionized water.
In one embodiment of the invention, the glycerin, the aloe extract, the coconut oil derivative and the xyloside derivative are respectively extracted and fully mixed according to the parts by weight, then the ethylene glycol monobutyl ether, the fatty acid polyoxyethylene ether, the lemon oil and the anionic surfactant are dropwise added and mixed with the deionized water, and finally the sodium alginate is added to carry out the pH value balance, so as to obtain the glasses cleaning solution. Wherein the aloe extract and coconut oil derivatives can enhance the cleanliness of the lens surface, remove oil stains, and improve the cleaning effect.
